SHUTTLE EMBROIDERING-MACHJN.

' Application filed April 1,

vplurality of'strips of fabric simultaneously.4

lVhile ithas been possible in the past to embroider on two separate strips of fabric, no machine has been found which is practical that will embroider a greater number of strips of fabric than two with any degree of success.

\An Object, therefore, of this invention is to provide a device which will embroider not only a plurality ofstrips of fabric in the same vertical plane, but also a plurality of strips of fabric in different vertical planes.

Another ob'ect of this invention is to :proy vide means or. supporting a plurality lof strips of fabric in different planes'in vertical staggered spaced relation, whereby acp cess may7 be had conveniently to the different strips of fabric, and with means for embroidering on all of said strips of fabric` simultaneously.-

A further object of this invention 1s to provide' an embroidering machine in which the shuttle elements are interposed between a plurality of strips of fabric, with the needle elements disposed outsideof the strips of fabric and cooperating with the shuttle elements. y v

A still further object of this invention is to provide a shuttle embroidering machine with borers for removing portions of the fabric with means for displacing the shuttle elements during the boring operation, and driving connections for. allowing for this displacement.

These and further objects, together with the construction and combination of parts, will bo more fully doseribcdfhereinafter and particularly set forth in the claims.4

Reference is to be had toy the accompanying drawings forming a part of this specification, in which similar characteis of reference indicate corresponding parts in all the views, and in which- Figure 1 is an end View in elevation Fig.

2 is a\contracted side vieW in elevation; Fig. 3 is a detail view of ysome of the shuttle elements; Fig. 4L is a horizontal section showing the mechanism for manipulating the b oring elements; and Fig. 5 is a detail view of 'the mechanism for.driving the boring eiements.

Referring more particularly to the sepa'- rate parts of this invention as embodied in the form shown in the drawings, l indicates a-main supporting frame, on WhichA is float- Alngly supported in any suitable manner, such as is common in various types ofembroiden ing machines, a fabric fra-me 2. This fabric frame is peculiar, in that it is provided with of which is adjapted to support one or more strips of fabric, and in the case of a plurality, the strips will be vertically-spaced. As

strips of fabric on each reach, and have indic'ated the strips of fabric by the numerals 5, 6, 7 and 8. The strips'of fabric lare supported on the frame in stretched condition, by means .ofrollers 9, arranged in pairs. It Ais to be noted that the rollers are so arranged .that the strips Of fabric on thereach will be staggered relative to the strips Of fabric o`n the reach 4; that is to say, the strips of fabric 7 and 8 are disposed in alinement with the spaces between and to the side of the strips of fabric 5 and 6. The purpose of this is lto permit any one of the strips of fabric to be accessible without interfering with the Others, so that in. case of breakage of threador the like, the damage can be form of my device, I have located the shuttle elements in between the strips of fabric in have disposed them between the reaches 3 iand 4. In this instanceTI show the shuttle mechanism in the form of aI movable .frame 10, having shuttle bars 1l, 12, 13 and 14, one for each strip'of :fabric and arranged in stag- 10. On each of these bars, there is provided the number varying with the number of needles to be used and the number of reproductions of the design to be made on each strip of fabric.

In order to operate the shuttle bars 11 to 14, and thus the shuttles, these bars are provided with arms 114, which yare provided with verticallyfdisposed pins 15,v which engered vertically-'spaced relation on the frame.

a plurality of shuttles of any suitable type,

a plurality of vertical reaches 3 and 4, each shown in the drawings, I have provided two readily ascertained and repaired. -n this v different vertical planes, that is to say, I

si tig. i)

M is driven the' shafts B2 and 33 br 1. W and ftd, secured to shatts la and o gage in vertical openings in links lb". This arrangement is for the purpose of allor/ing .the-vertical 'movement ot the shuttle traine Without disturbing,r the drive ont the shuttle bars, ivhich is utilized' for a purpose to'be described hereinafter. The links i6 are provided vvithpins 1'?, which engage in caro. grooves provided in cams 18 disposed on a shaft 19.' For the purpose et guiding the lll motion 'ot' the iinls 16, these links pro vided with slots 2O,` which engage the shaft 19, and thus. prevent any Wabbling, and at 'the same time hold the pins l? in the cani grooves.

The shaft 19 may be Adriven in any suitable manner, as by being provided with a bevel 'gear 2l, which meshes Wit-li. a corresponding bevel gear 22 on a shai't 23, which may be driven iro-in any suitable source et @il power, as indicated by 'a belt pulley' Cooperating -vvith the shuttles on the staggered bars, there are provided of needles 25, one tor each shuttle. These needlesare arranged in horizontal series on Z needle bars 26, 27, 28 and 29, one for each strip of fabric. The needle bars 26 to may be driven in unison in any suitcbie manner, as by havingl links 30 at each id,

engaging1 cains 3l on cam shafts and 30 The cams 31 are similar to the cains 18 above mentioned and shown in detail in 1 Fig. 3, that is, each cani 31 is provided with.

a cam groove engaged by a pin on the corresponding link 30 so that When then cams l-are rotated a reciprocating motion is ley driven by unison.

ln order to increase the artistic etliect oi the embroidered fabric, it is etten desirable to produce apertures therein, so as to have im an ,openvvork effect. For this'` purpose, l

have provided series ot borers 37 ,connected to boring bars and forming the boring olevniente 38, 39,40 and il corresponding to each of the strips of fabric. These boring 55 elements; that is Vto say, the boringu bars therefor, as Will be seen by reference to Fig.. l, are provided with l1orizontallydisposed shafts 43 and 4st, slidingly mounted in the traine, so as to permit -the movement ot each of the boring bars uniformly at both ends. ln the case of the boring elements 38 and 39, the shafts d3 and le are pivotally connected to eccentric rods 45 and t6 'which are given motion by :means oit eccei A?" C, The

'ni/ents and lli, through the intermediary or eccentric links 59. Similarly, to the opbosite'sidc, the bell crank levers $56 are connected by linksv GOto bell crank, levers (il, so as to nieve a shaft 62'in unison with the shaft 5i'. The shaft 62 has also eccentrics 63, one :tor each of' the boring elements 4i@ and el, which areoperat-ively .connected to the' shafts i3 by eccentric rods 6ft. 'llie rod may be adjusted by a lever 65, and locked in' any adjusted position by means ot a pin G5, which is adapted to engage in one of a plurality et' openings 67 in an arcuate loclt bar Y it will be seen by manipulation of the lever that the boring elements on both sides oit the icating fabric frame 2 may be swunq in unison toward or from the strips ot fabric. lhe shafts 49,50 and 62 and 57 are provided on. theirl lower ends With` bevel gears 69, which mesh with bevel gears 70 on shafts 7l.l rlhe connection of the bevel gears 70 to the shafts 7l will be seen by reference to Figa 5.4 rihe bevel gears Y0 are connected by means ot a spline 72, so that each one is :tree to slide on its shaft against the tension ot'4 av spring '73. willthus be see'n that by manipulating the lever 65 tour gears 69 will be swung into engagement with the four gears T0, and thus be driven from the shafts 7l, vvhich are connected by gearingr 74, so as to be driveny in unison. from a common. source of power 75, which is indicated by a belt pulleyvon one of the shafts .71. It the gears G9 are only just forced into engagement with the gear 70, they will 'form a driving connection between the'inain drive and the boring elements 38 to al, so that the latter will be reciprocatedv in the'strips of fabric jto 8 and produce a 'hole of minimum size. lt',

hweveig the lever 65 is manipulated a sutlicient distance to compress the spring; 73, the' boi-ers 37 will be brought closer 'to the strips kof fabric,y and, inasmuch as these borers are tapered, they will produce openings et greater or less, extent, according to the amount which the springs Z3 are compressed.

lWhen the boring mechanism is in opera tion, it is desirable that the shuttle bars and the shuttles thereon should be drawn out of orative alinenient with the needles. For carnose, the shuttle traine is lowered by los' ilo

the above description. When it is desired to embroider on the various strips of fabricthe floating fabric frame 2 is manipulated as is common in such types of embroidering machines, by means of a pantograph (not 1 shown), so as to follow the predetermined design. The needles 25 arle driven by the mechanism so as to coperate with the shuttles 13, thereby not only reproducing onl each fabric a plurality of representations of the same design, but Vreproducing this design on several strips of fabric, not only in the same plane but in different vertical planes. Then it is desired to bore openings in the fabric, the shuttle frame is lowered by manipulating the crank 7G, and the gears 69 swung into engagement4 With the gears 70 by manipulating the lever 65, the extent of movement of which will control the size of the opening.

It will thus be seen that there isprovided a simple and eilicient machine, in which the shuttles are located between the reaches of the floating frame and cooperate with the needles to produce a plurality of copies of the saine-design on a plurality ofstrips of fabric located in the same and diderent planes, and it will be further seen that all of the mechanism is simple and readily accessible, so that the device may work smoothly and efficiently.

Vhile I have shown one embodiment of my invention, I do not wish to be limited to the specific details thereof, but desire to be protected in various changes, alterations and modifications which may come within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentfl.A The combination with a supporting frame for supporting' a plurality of strips of fabric arranged in different vertical planes, or shuttle mechanism interposed between said strips of fabric, needle elements cooperating with said shuttle mechanism, arranged on the opposite sides oi said strips of fabric from said shuttle mechanism, means for driving said needle elements, boring mechanism adapted to produce openings `6(1 in said strip of fabric, said shuttle mechanism being movablev into and out of coperative relation with said needle elements, and means for manipula-ting said shuttle mechanism so as to be out of coperatio'n with said 65 needle elements when said boring mechanism is in action.
